spl: implement CRC check on U-Boot uImage
SPL currently does not check uImage CRCs when loading U-Boot.
This patch adds checking the uImage CRC when SPL loads U-Boot. It does
this by reusing the existing config option SPL_CRC32_SUPPORT to allow
leaving out the CRC check on boards where the additional code size or
boot time is a problem (adding the CRC check currently adds ~1.4 kByte
to flash).
The SPL_CRC32_SUPPORT config option now gets enabled by default if SPL
support for legacy images is enabled to check the CRC on all boards
that don't actively take countermeasures.
